Seal-O-Grip Unions are
air-inflatable connectors for low-pressure fluid or mud suction
and return lines. The Seal-O-Grip carbon steel body welds in
place on mud tanks or manifold pipe. A leak-tight seal is achieved
with rig supplied compressed air, even if the connecting pipe
is not perfectly aligned. The oil and abrasion resistant NBR
pneumatic tube can be inflated up to 200 psi against the outside
diameter of the connecting pipe, speeding field set-up and eliminating
the need for low pressure flanged connections.
